An ink-like midnight blue leaning toward deep indigo, almost black in low light with a subtle violet undertone.

Pairs beautifully with warm metallics, soft neutrals, and muted pastels to create elegant contrast. Use sparingly to add weight and formality, or broadly to establish a contemplative, modern atmosphere.
